* tc-xgate.h: Defined tc_frob_symbol.
* tc-xgate.c (xgate_frob_symbol): Wrote new function to mark
symbols as being XGATE by setting st_target_internal value.
bfd/
* elf32-xgate.c (elf32_xgate_add_symbol_hook): Added a temp patch
that forces st_target_internal to equal 1, since tc_frob_symbol
seems to need adjusting.
